How to Wash Jeans So They Stay in Mint Condition

If you have a pair of dark-wash indigo jeans or black denim that you want to keep in like-new condition, wash your jeans inside out and add a splash of vinegar to help the dye from crocking too much. Think of it like dyeing Easter eggs — this helps lock in the dye. Adams-Geller also recommends using dark Woolite in cold water on a gentle cycle to prevent fading.
